XSLT with namespaces: Copy template omits attributes - xslt

Question

Applying the standard XSLT copy template,
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
to the JBoss AS 7 standalone.xml, leads to loss of parameters:
<?xml version="1.0" encoding="UTF-8"?><server xmlns="urn:jboss:domain:1.1">
<extensions>
<extension/>
<extension/>
instead of
<?xml version="1.0" encoding="UTF-8"?><server xmlns="urn:jboss:domain:1.1">
<extensions>
<extension module="org.jboss.as.clustering.infinispan"/>
<extension module="org.jboss.as.configadmin"/>
Why?
How can i Make it copy everything?
XSLT transformation is done by Maven XML plugin.
The whole template:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ds="urn:jboss:domain:datasources:1.0"
xmlns="urn:jboss:domain:1.1"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="*|#*|node()">
<xsl:copy>
<xsl:apply-templates select="*|#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Answer 1

Your template appears to be working correctly.
I modified it and the XML to show that is working:
<?xml version="1.0" encoding="UTF-8"?>
<server xmlns="urn:jboss:domain:1.1">
<extensions>
<extension module="org.jboss.as.clustering.infinispan"/>
<extension module="org.jboss.as.configadmin"/>
</extensions>
</server>
Run with this XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ds="urn:jboss:domain:datasources:1.0"
xmlns:so="urn:jboss:domain:1.1"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="*|#*|node()">
<xsl:copy>
<xsl:apply-templates select="*|#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="so:extension">
<xsl:copy>
<xsl:attribute name="testing">just for fun!!</xsl:attribute>
<xsl:copy-of select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Produces:
<?xml version="1.0"?>
<server xmlns="urn:jboss:domain:1.1">
<extensions>
<extension testing="just for fun!!" module="org.jboss.as.clustering.infinispan"/>
<extension testing="just for fun!!" module="org.jboss.as.configadmin"/>
</extensions>
</server>
Here's the output run with your original XSL:
<?xml version="1.0"?>
<server xmlns="urn:jboss:domain:1.1">
<extensions>
<extension module="org.jboss.as.clustering.infinispan"/>
<extension module="org.jboss.as.configadmin"/>
</extensions>
</server>
I downloaded the full JBoss standalone.xml, ran your XSL, and here's the diff of the input and output XML:
so zacharyyoung$ xsltproc so.xsl so.xml > output.xml
so zacharyyoung$ diff so.xml output.xml
1,2c1
< <?xml version='1.0' encoding='UTF-8'?>

> <?xml version="1.0"?>
